Signaling and configurations of enhanced subslot-based pucch repetition

Abstract

A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a radio resource control (RRC) message comprising first information used for indicating a repetition type from a set of repetition types for Physical Uplink Control Channel (PUCCH) transmission(s). The receiving circuitry is also configured to receive an RRC message comprising second information used for indicating a number of PUCCH repetitions or a set of numbers of PUCCH repetitions. Further, the receiving circuitry is also configured to receive, based on a detection of a Physical Downlink Control Channel (PDCCH) carrying a downlink control information (DCI), third information (in the DCI) used for indicating a selection or adjustment of the number of PUCCH repetitions. The UE also includes transmitting circuitry configured to transmit, to the base station, PUCCH transmission(s) according to the first information, the second information, and the third information.
